We propose "crystal diagram" as a base for making high-density diagrams. In high-density railway sections such as metropolitan commuter lines, there is a great demand for increasing train density in order to relieve traffic congestion. However, it becomes more difficult to shorten train headway, as the track layout, train type and so on become more diverse. Therefore, making train diagrams needs the expertise of skilled specialists. In order to raise the train density, this paper aims to

It is a crystal diagram to refer to one cycle of the pattern and station diagram whose periodic time is shortest, on the assumption that instructions to all trains in one period are fixed. In practice, we obtain the effective results for operation planning, train dispatching and equipment design when we derive the crystal diagrams of model cases.
